Tunnel Broker

On the IPv6 > Tunnel Broker tab you can enable the use of a tunnel broker. Tunnel brokerage is a service offered by some ISPs which allows you to access the Internet using an IPv6 address.

Note – You can either have 6to4 enabled or Tunnel Broker.

Sophos UTM supports the following tunnel brokers:

  • Teredo (only anonymous)
  • Freenet6 (by GoGo6) (anonymous or with user account)
  • SixXS (user account necessary)
  • Hurricane Electric (user account necessary)

To use a tunnel broker, do the following:

  1. On the Tunnel Broker tab, enable the use of tunnel broker.

    Click the toggle switch.

    The toggle switch turns green and the Tunnel Broker area and the Advanced area become editable. The tunnel broker is immediately active using anonymous authentication at Teredo. The connection status is displayed on the Global tab.

If you use SixXS tunnels and the IPv6 connection gets lost the SixXS tunnels do not restart automatically. In this case check the log files which appear in Logging & Reporting > View Log Files > Today's Log Files.
